Question 112

The following description of the characteristics of multi-instance CE is ?

Since the MCE device is already bound to the VPN, there is no need to bind the VPN on the PE connected to the MCE device

The MCE device can determine the source of the routing information according to the interface that receives the routing information, and maintain it in the route forwarding table of the corresponding VP.

MCE is implemented by creating their own routing forwarding tables for different VPNs on the MCE device and binding to the corresponding interface o

Configuring MCE enables a CE to connect to multiple VPNs at the same time, which can not only completely isolate the service between different VPN users, but also reduce the input cost of network equipment.

Question 113

Users within a typical VPN can only communicate with each other, not with Internet users, and with Internet. But VPN individual sites may have access to internet's needs. The correct description of the implementation of VPN interconnection with internet is ?( Multiple choice questions).

is implemented on the user side, and the CE is directly connected to the Internet. Each user site can be connected to the Internet separately, that is, the CE of each site is configured with a default route to the Internet.

Implementing a complex implementation on PE and having security implications, PE devices may be subject to Dos attacks on the Internet.

Implemented on PE, the PE device issues a default route to the CE to the Internet and adds a default route to the VPN instance routing table pointing to the Internet Gateway o

Implemented on the user side, the implementation method is simple, and the public network and private network routes are isolated, safe and reliable.

Question 120

NSF (Non-StoppingForwarding ) and non-stop circuits are transmitted NSR (Non-Stopping Routing) are two highly reliable solutions, and the following statement is correct

After NSR enablement, if the business batch backup has not yet ended, a master board failure occurs, the NSR cannot be completed

NSR backers require the ability to support NSR through specific message negotiation

After NSF is enabled, the router is switched back, and the routing table and forwarding table remain unchanged, so traffic is not lost during grf time

NSF routers do not need to negotiate the ability to support NSF through specific messages
